Electro pneumatic control system for emergency and emergency brakes for at least one railway vehicle

摘要

An electric pneumatic control system (300) has been described for emergency and permanent brakes.Electric pneumatic control systemBrake pressure generating module for producing brake pressure to brake groupWeight signalEmergency brake request signalThe brake pressure generating module (311)311 ',Each of the brake pressures produced by309 ',Receiving a plurality of actual pressure signals indicative of the pressure values ofAn emergency pressure monitor and a control unit (301) that provide an emergency brake request signalAn emergency pressure module that produces an emergency brake pressure andWhen the emergency brake request signal indicates no emergency brake requestTo generate a corresponding brake pressure based on the normal brake request signal and the weight signalAlso, when the emergency brake request signal indicates an emergency brake requestBased on the emergency brake pressure demand signalTo produce brake pressureA brake control unit (307) which provides a pair of control signals andWhen closedThe brake control unit 307 connects the pair of control signals to the brake pressure generating moduleIn addition, when openA first emergency switching device (318) having a pair of contacts (317) for preventing the connection of pairs of control signals from the brake control unit to the brake pressure generating module (311) is provided.Diagram
